A novel thermal coupler apparatus and method to couple a cryocooler or another cooling device to a superconducting magnet or cooled object allows for replacement without a need to break the cryostat vacuum or to warm up the superconducting magnet or other cooled object. A method uses a pneumatic actuator for coupling, and a retractable mechanical actuator for uncoupling. Mechanical closing forces are balanced between the intermediate temperature and low temperature cooling surfaces and do not transfer to the cooled object. The pneumatic actuator provides permanent control under mechanical closing forces in the thermal coupling.
