The key should not be holding anything, it's only there to make sure the flywheel is positioned correctly. If it's working loose, then either the key or the keyway is worn/battered to hell. As long as the flywheel is positioned correctly and is staying where it is, then everything is ok.

If the flywheel is moving on the end of the crankshaft, then you've got all sorts of other problems that are nothing to do with the key.

Sounds like the taper is a bit fuXX0red. Lap it back in.

Also remember to degrease both parts of the taper with solvent before fitting. Any oil on there and it'll just spin up.
