According to a first aspect of the invention we provide an apparatus for torsionally coupling a threaded fastener and a torque output device including: - a first coupling member (100) : rotatably and threadedly engagable with the threaded fastener; rotatably and taperedly engagable with a second coupling member (150); non - rotatably engagable with an action portion of the torque output device; the second coupling member (150) non - rotatably engagable with a reaction portion of the torque output device; and wherein the first coupling member (100), when rotated by the action portion of the torque output device, applies a load to the threaded fastener. |
