Each housing part has one or more concave cavity wall portion(s) for rotatably retaining the coupler or a coupler segment in the cavity or in a housing part cavity portion. The coupler or each segment has one or more convex outer surface wall portion(s). The concave cavity wall portion(s) slip fit engage the coupler or coupler segment convex surface wall portions and rotatably retain the coupler or segment(s) within the housing cavity or housing part cavity portion.
