Abstract: A locking clutch to selectively transmit torque from a stator of a downhole tool to a rotor of the downhole tool includes at least one locking pawl disposed upon the rotor, wherein the at least one locking pawl comprises a load path, at least one pivot axis, and a mass center, wherein the at least one locking pawl is biased into an engaged position by a biasing mechanism, wherein the at least one locking pawl transmits force from the stator to the rotor along the load path when in the engaged position, and wherein centrifugal force urges the at least one locking pawl into a disengaged position when the rotor is rotated above a disengagement speed.
