Go and get a lampholder/socket that is touch safe -- yours is old, and bad, and was never designed to be placed in a position where it could be poked when turned on. In fact, yours is bad enough that it leaves the screw contact (neutral) exposed instead of having any sort of shell around it. No wonder you're getting bit by it!
I don't recommend using an adapter for anything other than a temporary situation.
Now, the main question is: Is this safe?
The problem here is that manufacturers blindly apply equivalency tables when the shouldn't.
Picture a more common situation - a side table lamp with a small shade. Typically you'll see a warning sticker saying "Don't use a bulb greater than 60 watts/9 W LED."
This is due to a mistaken idea that an incandescent and an LED are in all ways equivalent. However, they are not. An incandescent bulb is about 2% efficient in that it's output is about 1.2 Watts of light energy, and 58.8 Watts of heat and IR energy. It is this heat energy which is the reason for the safety sticker. More heat output, and you start to melt or burn the shade, which is a fire hazard.
Now, without getting into the efficiency of LEDs, it's obvious that 9W is significantly lower than 58.8 Watts. That is, there is no possible way the LED bulb can produce enough heat to damage the lampshade and present a fire hazard.
For completeness, we should also discuss the input side. Obviously, putting in a megaWatt bulb of any sort will, in normal circumstances flip a breaker or blow a fuse. In abnormal circumstances, it can melt the wiring in your wall or the internal workings of the socket and any integrated switch assembly. One would hope that all lighting fixtures could handle any reasonable load, with cheaper and cheaper products on the market, there may be smaller gauge internal wiring or other components that might not be able to handle the current draw of a 150 w bulb, thus the warning. (But, the main reason is still heat and fire.) But, even if this is true, 9W is well below the spec, and it is safe to use a 9W bulb in a fixture designed for a 60W incandescent.
TL;DR: If a fixture is rated for a 60 W bulb, any bulb of equal or lower wattage (within reasonable geometry) will be safe in that fixture.

It looks like the Hue system doesn't have any candelabra sized bulbs. I don't see a Hue switch that would let you control the fixture as is. All the Hue system bulbs look large.
There are adapters that will let you use standard bulbs in an e14 socket:
I'm just not sure the bulb will fit in the fixture with the adapter - looks like it may be too small even without the adapter. It might turn out to be easier to change the fixture.
(BTW, if you are in the US, you may want to check that it's really E14 and not E17 intermediate size socket.)
