Zusammenfassung:A clockspring (10) having a device for determining if the clockspring is centered. The clockspring has a housing (16) defining a first central aperture and the housing also has a radial wall (18), a hub (14) is carried in rotatable relation in the first central aperture (27), a coiled ribbon cable (58) having a first end and a second end with the first end being connected to a first connector (60) carried by the housing, and the second end of the coiled ribbon cable being connected to a second connector (62) carried by the hub (14), the hub being rotatable only a maximum number of revolutions before the coiled conducting means becomes completely wrapped or unwrapped around the hub (14), a pawl (72) mounted to the hub, a counter wheel (84) rotatably attached to the housing and having a plurality of teeth (92) which extend from the counter wheel for incremental engagement with the pawl (72), the plurality of teeth (92) being equal in quantity to the maximum number of hub revolutions, each tooth being labeled to indicate the amount and the direction of hub rotation needed for centering the hub with respect to the housing, a wave washer (86) frictionally mounted against the housing and the counter wheel, a counter cover (100) is mounted over the counter wheel so that no more than two teeth (92) from the counter wheel (84) are exposed at any given time.
