ABSTRACT:
A coupling connects a first member and a second member. The first member has a first interlocking member extending radially outward from an outer circumferential surface of an axial end. The second member includes a second interlocking member extending radially inward from an inner circumferential surface of an axial end. The axial end of the first member is inserted into the axial end of the second member, such that the first interlocking member is inserted past the second interlocking member. The first and second members are then rotated relative to one another to a locked angular orientation, in which the first interlocking member is interlocked with the second interlocking member to prevent relative axial movement of the first and second members. A key is then inserted into a keyway in the first and second members to lock the angular orientation, thereby coupling the first and second members to one another.
