Abstract
A sleeve is retained to a shaft without the use of a keyway through at least one end connection that has a preferably flat face with one or more projections from the flat face. Rounded projections are preferred. The projections go into shape matching depressions on the sleeve. Alternatively the sleeve can have the projections and the end retainer can have the depressions. The end retainer is spring loaded for axial deflection in the event of an over-torque. If that happens there is planned for slippage until the condition is alleviated at which point the spring bias is able to again match a projection to a depression for continuing tandem driving of the shaft and the sleeve. The sleeve is preferably carbide and resides in a carbide bushing.
