This invention embodies a device and a method for transferring volatile fluid from a container to a receiver using the said device, the said device comprising an adapter configured to be secured to said container and a receiver sub assembly adapted to be secured to said receiver said adapter and receiver sub assembly provided with components complementary to one another and movable sealing elements adapted to selectively engage with one other such that in an operative receiver filling configuration, movement of the adapter relative to receiver sub assembly leads to first open the sealing element in receiver sub assembly to connect fluid path to the receiver and next open the sealing element in the adapter to connect a fluid passage path from the container to the receiver sub assembly, and in an operative stop-filling configuration, the movement of adapter relative to receiver sub assembly in reverse direction leads to close the sealing element of the adapter prior to closure of the sealing element in the receiver sub assembly characterized in that in an operative configuration the adapter and the receiver sub assembly are configured to be linked to one another by engagement of said complementary components and relative movement of the components of said receiver sub assembly sealing element is linear along its axis and of the said adapter sealing element is angular/rotational around its axis.
