An auto-engageable coupling is disclosed for use in a pumping system that includes an electric motor and a pump driven by the electric motor. The auto-engageable coupling permits the transfer of torque from the motor to the pump but prevents the pump from applying torque to the motor. In some embodiments, the auto-engageable coupling includes a drive cup connected to a motor shaft driven by the motor, an output cup connected to an output shaft, and a drive bearing clutch connected between the drive cup and the output cup. The drive bearing clutch is configured to lock the drive cup and the output cup together when the motor shaft is driven in an intended direction. The auto-engageable coupling optionally includes a brake bearing clutch configured to resist the rotation of the output shaft in an unintended direction.
