The superior surface of the coupling member and an inferior surface of the collar form an engagement interface configured to constrain rotational movement of the inserter and the collar about the engagement axis. The engagement interface may include one or more protrusions on one of the superior surface of the coupling member and the inferior surface of the collar and one or more recesses on another one of the superior surface of the coupling member and the inferior surface of the collar. The engagement interface may include an interlocking coupling that may include a plurality of both teeth and valleys on each of the superior surface of the coupling member and the inferior surface of the collar, the teeth and valleys of each of the superior surface of the coupling member and the inferior surface of the collar intermesh when the coupling member and the collar abut.
