    Abstract: A socket assembly for rotating a nut having an annular body with a radially inner edge defining a torque transferring surface, the socket assembly has: an intermediate socket (220) extending axially relative to a central axis (A) between a proximal end and a distal end, the proximal end of the intermediate socket (220) engageable by a tool for rotating the intermediate socket (220) about the central axis (A); and socket segments (211) detachably connected to the intermediate socket (220) in a circumferential array about the central axis (A), a socket segment of the socket segments (211) having a nut-engaging end projecting radially outwardly relative to the distal end of the intermediate socket (220) and engageable with the torque transferring surface of the nut to transfer a torque from the intermediate socket (220) to the nut via the socket segments (211).

    Abstract: A stator is provided for a progressive cavity device. The stator includes modular stator segments connected together. Each stator segment includes a front surface, a rear surface, and an internal helical cavity extending longitudinally from the front surface to the rear surface. Each stator segment also includes a set of bolt holes extending longitudinally from the front surface to the rear surface, and a set of connection holes opening at the front surface and extending at least partially longitudinally from the front surface to the rear surface. Bolts, inserted through the bolt holes into connection holes of an adjacent stator segment, connect the stator segments and align the internal helical cavities to form a continuous helical chamber.
