ABSTRACT Disclosed is a coupling for joining two elements with their central axes aligned so that turning one element around its central axis will turn the other element. The coupling comprises a raised portion on an end of one element and a mating recessed portion on an end of the other of the elements adapted to engage with the raised portion. The raised portion com- prises a substantially circular disc-shaped base portion, an uneven number of portions integrally formed with and protuberant above the base portion and concentrically located within one surface thereof and a similar number of ribs integrally formed with the base portion and alternating with the protuberant portions and extending outwardly thereof. Each rib member extends substantially from a radius of the base portion to the outer periphery thereof in a substantially symmetrical configur- ation with the remaining ribs. The recessed portion of the other of the elements comprises a recessed, substantially cir- cular recess portion of similar diameter to the base portion, an inwardly projecting protuberant recess substantially con- centric with the circular recess and of similar dimensions to the protuberant portions of the raised portion of the one element, and a plurality of flutes projecting inwardly of the protuberant recess and positioned for mating engagement with the plurality of ribs on the raised portion of the one element.
