Phillips screw drivers are supposed to cam out, by design..
to prevent overtightening aluminium fasteners.
It's even in the patent.

"ost power screw-drivers are provided with a slipping clutch which may be adjusted to begin slipping before the driving torque is great enough to break the screw or to ream the recess, but unfortunately these clutches are subject to a number of variables so that they cannot always be given or maintain an exact setting. It is the tendency of the operators to set them to slip at too great a torque rather than too little to be sure of driving all screws completely home. The small amount of throw-out retained in the present combination of recess and driver bit is proper to overcome the difliculties explained at the beginning of this specification. Thus there is sufiicient throw-out effort to force the driver clear of the screw recess on the application of excessive driving torque and thereby prevent reaming or marring of the recess and any damage to the driver blade."
If you wanna apply torque, you should get Pozidriv instead. Not Phillips.
Or Phillips II which is designed not to cam out
