A handle 10has a grip 12 coupled to a rotatable shaft 14 that extends in a longitudinal dimension and has multiple shaft protrusions 21-24. A wall 62 has an aperture for receiving a portion of the shaft; at least one retainer 70configured to retain the portion of the shaft in the aperture. The retainer or retainers have multiple stops 81-84 for alignment and engagement with the shaft protrusion in order to prevent the shaft from withdrawing from the aperture in the wall. Multiple retention protrusions 71-74prevent the shaft protrusions from misaligning with the stops.
