Abstract
A unidirectional torque-transfer coupling is disclosed. The coupling may include a first ring and a second ring that share a common axis, wherein the first ring is configured to rotate about the common axis from a first position to a second position; a first member extending from the first ring; and a second member extending from the second ring, wherein, when the first ring is in the second position and a valve coupled to the second ring is in an open position, the second member engages the first ring, and wherein, when the first ring moves from the second position to the first position, the first member causes the second ring to rotate in a same direction as the first ring Furthermore, when the first ring is in the second position, a valve is substantially unrestricted by the first ring with regard to moving to an open position.
