A coupling mechanism for a molten metal processing system includes an elongated shaft having an upper axial end and a lower axial end. A passage having a torque facilitating shape extends through at least a portion of the shaft. The upper end of the shaft tapers inwardly and forms a tapered seat. At least one channel is machined into an outer surface of the upper end of the shaft. The channel has a first portion extending longitudinally downward from a top surface of the shaft and a second portion extending from the first portion at an angle greater than 90° relative to the first portion. A coupling member, for coupling the shaft to a drive system forming a bayonet coupling. The cavity of the coupling member tapers outwardly forming a mouth which engages the tapered seat of the shaft in a sealing relationship.
