TORQUE COUPLING SYSTEM Abstract A torque coupling system includes an impeller (13) that is connected to one end (26) of an impeller shaft (15) without the use of threads. The connection is made by cement and dowels (38). A drive system for the shaft (15) includes a hollow coupling (42) into which the other end (24) of the shaft (15) can be fitted. The shaft (15) includes longitudinally extending slots (40) formed at its end (24). The coupling (42) includes spaced, longitudinally extending keys (44) adapted to be fitted into the slots (40) formed in the shaft (15). The drive system also includes a torque limiter (60) that is connected intermediate the coupling (42) and a drive motor (16). If the drive motor (16) is an electric motor, the motor (16) can be provided with automatic shut-down circuitry that is activated in the event of a current/torque overload. Visual and aural alarms are provided to alert the user that a shut-down has occurred.
