Abstract
A rotatable member is mounted through substantially normal bearing structure onto a shaft in rotating relationship therewith. A torque limiting drive device, such as a spirally coiled spring, is fitted between the rotatable member and the shaft for permitting transmission of torque therebetween. The spring permits only a limited torque to be transmitted between the rotatable member and the shaft such that, if this torque is exceeded, then the spring slips with respect to the rotatable member to thereby permit relative rotation between the shaft and the rotatable member.
