A handle has an inner hub member which engages a shaft and rotates about a longitudinal axis therewith, an outer hub member which is disposed around the inner hub member and is coaxial therewith, and resilient material disposed in a space between the inner and outer hub members. The resilient material effects the transfer of rotational movement between the inner and outer hub members, and under normal operating conditions, the outer hub member is generally coaxial with the inner hub member and rotates in a tangential direction to effect the rotation of the inner hub member and the shaft. Thus, upon the rotation or movement of the outer hub member in a direction other than the tangential direction which results in the outer hub member extending along an axis angled to the longitudinal axis of the inner hub member, the inner hub member maintains its direction along the longitudinal axis by virtue of the resilient material disposed between the inner and outer hub members.
