Claim:
1. A drug reconstitution device comprising a single use disposable liquid transfer unit ( 18 ) and a reusable control and drive unit ( 16 ) removably connectable to the liquid transfer unit, the disposable liquid transfer unit including a housing ( 26 ), a docking interface ( 30 ) configured for coupling at least one of a first and a second constituent containers ( 2 , 4 ) to the housing ( 10 ), and a pump engine ( 28 ) and fluid flow system ( 37 ) configured for transferring liquid from the first constituent container ( 2 ) to the second constituent container ( 4 ), the control and drive unit comprising a pump drive ( 22 ) configured to drive the pump engine during a fluid pumping action, the pump drive comprising a transmission output coupling ( 34 ) removably engaged with a transmission input coupling ( 50 ) of the pump engine ( 28 ) when the liquid transfer unit and control and drive unit are connected, wherein the pump engine is configured as a rotary pump and comprises a rotor rotatably moveable in a stator and integrated with said transmission input coupling ( 50 ), the transmission input coupling removably engageable with a transmission output coupling of the pump drive.
