Abstract
A progressing cavity pump/motor includes a stator tube (), a rotor () within the stator tube, and a coupling assembly () interconnecting the upper and lower rotor sections. The coupling includes a drive adapter () and a socket adapter () for transmitting torque between the upper and lower rotor sections, and at least one alignment surface () in cooperation with a mating surface to rotationally position the drive adapter within the socket adapter at a selected circumferential position. The pump/motor may be reliably assembled in the field while maintaining precise axial and rotational positioning of the rotor sections.
