Abstract

A torque transmitting mating component for a mating assembly which, during assembly, provides at least one degree of freedom of movement selected from radial, axial and angular movement comprises an outer member, an inner member and torque transmitting elements located between the outer and inner members. The outer member has a chamber extending inwardly from one end thereof which has a polygon-shaped cross-sectional configuration. The inner member is located within the chamber of said outer member and has external side faces which are arranged to provide a polygon-shaped cross-sectional configuration corresponding to that of the chamber. The inner member is substantially smaller than the opening and the outer member so as to provide a clearance gap between the side walls and the external side faces. The torque transmitting elements are mounted in the clearance gap and provide a torque transmitting interference between the external side faces and the side walls while permitting limited relative movement therebetween to provide at least one degree of freedom of movement of inner and outer members with respect to one another. One of the members is adapted to form a mating element which is self-aligning when being engaged with a complementary mating element of the mating assembly.
