The present invention broadly comprises a torque transfer apparatus for a torque converter including at least one connection element attached to an inner circumferential surface for a cover of the converter; a lock-up clutch, and at least one resilient element connected to the connection element and the piston plate. In one aspect, the transmitter may be configured to transmit a current data point and at least one previous data point, the current data point and the at least one previous data point corresponding to the detected one or more glucose levels. A motor is arranged at a position separated from the power receiving connector. In this regard, the number of bidirectional ports of an optical circuit switch can be increased allowing additional bandwidth to flow through the optical circuit switch.
