Claim 2:
3. The torque tool apparatus of claim 2, wherein the torque head assembly comprises a two-component square-nut adapter for servicing hydraulic cylinders with square piston-retaining nuts, wherein:
a first component of the two-component square-nut adapter is a square-nut adapter fixed jaw configured for demountable engagement into the flat narrow end and against the pair of opposed outward-extending sides of the frustoconical-ovoid-shaped aperture of the torque plate, wherein the fixed jaw has two faces set at 90°; and
a second component of the two-component square-nut adapter is a square-nut adapter movable jaw with one side configured to receive and cooperate with the end of the bolt, and the opposite side having two faces set at 90°;
whereby a square hydraulic cylinder piston-retaining nut of a hydraulic cylinder is demountably engageable with the torque head assembly by positioning two sides of the square piston-retaining nut against the two faces of the square-nut adapter fixed jaw and the other two sides of the piston-retaining nut against two faces of the square-nut adapter movable jaw and threadably engaging the bolt against the other side of the movable jaw.
