A coupling for a rotary arrangement. The coupling system includes a shaft (11) that has a proximal end (12) that includes an angled face (13). The system also includes a coupler (20) that includes an angled face (15) configured for engagement with the angled face of the shaft (11). The coupler (20) is coupled or attached to a rotary element (10) such that upon coupling of the rotary element (10) to the shaft (11) via the coupler (20), the rotary element (10) will rotate with the shaft (11) as opposed to relative thereto.
