1. A system, comprising:
a motor drive assembly including a pump motor, a first torque transmission mechanism operably coupled to and rotatable by the pump motor, a recirculation motor, and a second torque transmission mechanism operably coupled to and rotatable by the recirculation motor, the first torque transmission mechanism and the second torque transmission mechanism forming a portion of an exterior surface of the motor drive assembly; and
a fluid delivery assembly including a fluid pump, a first torque receiving mechanism operably coupled to the fluid pump such that rotation of the first torque receiving mechanism causes the fluid pump to dispense fluid, a valve, and a second torque receiving mechanism operably coupled to the valve such that rotation of the second torque receiving mechanism causes the valve to transition between a fluid dispensing configuration and a fluid recirculation configuration, the first torque receiving mechanism and the second torque receiving mechanism forming a portion of an exterior surface of the fluid delivery assembly,
the fluid delivery assembly configured to be removably coupled to the motor drive assembly such that, simultaneously, the first torque transmission mechanism is coupled to the first torque receiving mechanism in a non-mating orientation and the second torque transmission mechanism is coupled to the second torque receiving mechanism, the first torque transmission mechanism being configured to mate with the first torque receiving mechanism such that rotation of the first torque transmission mechanism causes rotation of the first torque receiving mechanism, the first torque transmission mechanism is configured to rotate relative to the first torque receiving mechanism from the non-mating orientation to mate with the first torque receiving mechanism while a housing of the fluid delivery assembly is coupled to a housing of the motor drive assembly, the second torque transmission mechanism being configured to mate with the second torque receiving mechanism such that rotation of the second torque transmission mechanism causes rotation of the second torque receiving mechanism.
