An input ring member rotatable about an input axis of rotation engages the input disk at an input contact patch. An output ring member rotatable about an output axis of rotation engages the output disk at an output contact patch. A sum of a length of a first input contact patch vector extending from the input contact patch to the disk axis of rotation and a length of a first output contact patch vector extending from the output contact patch to the disk axis of rotation is greater than a length of at least one of a second input contact patch vector extending from the input contact patch to the input axis of rotation and a second output contact patch vector extending from the output contact patch to the output axis of rotation.
