ABSTRACT:
A device for coupling a torque driver to a fastener that is to be driven on a workpiece by the driver, and for coupling the driver housing to the workpiece, has two nesting cylindrical barrels, one of which can be fastened to the driver housing and the other of which can be connected to a reaction structure which is clamped to the workpiece. The two barrels are coupled together for limited rotation relative to each other which facilitates placement of the device on the reaction structure and securing it in place thereon, and also provides a torque path for reaction torque from the driver housing through the two barrels of the device to the reaction structure and thence to the workpiece. The reaction structure has a series of positioning stops that facilitate quick and accurate positioning on the workpiece, and a power operated clamp for securely connecting the reaction structure to the workpiece.
