1. A coupling comprising:
a first component having a cylindrical outer surface;
a second component having a cylindrical inner surface coaxial to a longitudinal central axis of the outer surface of the first component;
first connection formations on the first component;
second connection formations on the second component and interacting with the first connection formations to prevent relative rotation of the components,
retaining teeth forming one of the connection formations;
longitudinal projections forming the other of the connection formations, distributed over a periphery thereof, mutually spaced, and extend parallel to the longitudinal central axis; and
transverse projections formed on the other connection formation and mutually spaced and distributed over the periphery thereof so as to prevent relative axial movement of the components.
