The present invention increases power efficiency in power FET applications with varying loads. The first transmitter may be configured to transmit through a first physical channel of a connector. As a first step, the bolt is first tightened to a predetermined snug torque. A first channel is defined by the first plate and the first lobe and the second plate and the second lobe with the rope moveable through the first channel wherein tension on the rope rotates the first plate and the second plate relative to each other thereby narrowing the first channel and impeding movement of the rope through the first channel.
