An adapter that bridges the connecting ends of a medication providing device and a fluid connector includes a housing shroud that is fitted at one end with a core and at its other end with an inner shroud. A catch hub is provided within the housing shroud to act against a flange at the core so as to non-removably maintain the core to the housing shroud. The core is rotatable relative to the housing shroud. Once the medication providing device is coupled to the core, additional rotational movement, in either direction, of the medication providing device would only cause the core to rotate freely relative to the housing shroud. The inner shroud has a catch mechanism that enables it to mate readily with a connector, if the connector is rotated in one direction. The catch mechanism is designed with one way teeth such that once the connector is fully mated to the inner shroud, further rotational movement along the coupling direction would cause the inner shroud to rotate freely relative to the housing shroud. The catch mechanism is further configured to allow the connector to be removed if it were to be turned in a counter rotational direction.
