A ball ramp mechanism is used to apply a clamping load to a clutch pack to rotationally couple an input shaft to an output shaft. The ball ramp mechanism is comprised of a control plate having a control extension radially extending therefrom and an activation plate having an activation extension radially extending therefrom and an intermediate plate disposed between the control extension and the activation extension where the control extension and the activation extension and the intermediate plate are frictionally rotationally coupled upon application of an electromagnetic field generated by a stationary coil acting through a rotating coil armature to activate the ball ramp mechanism. A gap sleeve contacts the control plate and the activation extension to limit the separation between the control extension, the intermediate plate and the activation extension. The activation plate is mounted to the input shaft through a first one-way clutch and the coil armature is mounted to the input shaft through a second one-way clutch when the first one-way clutch is oriented opposite to the second one-way clutch.
