Original Abstract Submitted
An electrical submersible pump assembly comprising a first section and a second section with an outer housing and a drive shaft. A coupling assembly comprising a coupling, a first and a second locking keys, and a plunger assembly mechanically couples the first drive shaft to the second drive shaft. The coupling is cylindrical in shape with splines configured to transfer torque from the first drive shaft to the second drive shaft. The plunger assembly extends the first and second set of locking keys from a key port in the first shaft and second shaft into a groove within the coupling. The coupling assembly is configured to transfer tensile stress from the first drive shaft to the second drive shaft in response to extending the first locking key in the first groove and the second locking key in the second groove of the coupling.
