Abstract

An apparatus for applying torque about an operational axis of rotation includes a first torque device member. In addition, the apparatus includes an actuator support configured to move radially relative the operational axis and configured to be restricted from rotating in a plane oriented perpendicular to the operational axis. Further, the apparatus includes a first torque actuator pivotally coupled to the first torque device member and the actuator support. Still further, the apparatus includes a rod or a second torque actuator pivotally coupled to the first torque device member and the actuator support. Moreover, the apparatus includes a second torque device member coupled to the first torque device member and disposed about the operational axis of rotation. The actuator support is pivotally coupled to the second torque device member and is configured to pivot about a first pivot axis towards and away from the operational axis of rotation.
