1. A tensioning device comprising:
a tensioning module including a piston and a tensioning housing supporting the piston for movement, the piston being operable to transmit force to a pulling member configured to engage a workpiece and to transmit a tensile load to the workpiece, the tensioning housing defining a tensioning port configured to receive pressurized fluid to move the piston from an initial position toward a tensioning position; and
a retract module including a retract housing positioned in a stacked configuration on the tensioning housing, the retract housing defining a retract port configured to receive pressurized fluid to move the piston from the tensioning position toward the initial position.
