Superglue will work. You just have to do it right. Take a bit of iso alcohol and an old toothbrush and clean the screw off. Take a bit of fine sandpaper and scuff up the screwdriver bit and then clean it with iso as well.

Then add a tiny bit of glue to the driver and a tiny bit to the screw. Then wait 1 minute, push the bit into the screw down hard, and leave it be for 30 minutes before turning.

This is much easier to leave balanced for that 30 minutes if you have just a bit and not the whole screwdriver to leave balanced.
