Abstract
An assembly for providing torque to an object in a wellhead. The assembly includes a body attachable to the wellhead and including a bore with a centerline. The body further includes a first set of pistons within cylinders oriented at angles offset from and perpendicular to the centerline of the bore. The pistons are moveable within the cylinders between a retracted position and an extended position where the pistons are extended into the body bore. The movement of the pistons between the retracted and extended positions imparts a linear force capable of rotating the object in the wellhead in a first direction.
