Use an Allan wrench the size of the screw hole in the driver. Insert the short end into the driver screw hole and use the long end of the wrench to GENTLY pry upwards. Position the wrench parallel to the driver not towards the outside or inside of the driver where the driver is weakest. Work your way around the driver holes one at a time prying gently a little at a time. I’ve done this many times and it works like a charm. Just remember to take your time and don’t force anything, just gently coax the driver out.
