1. A nozzle for coupling to and providing cryogenic fluid to a receptacle, the nozzle comprising:
a body including a front end and a back end, the body comprising:
an outer shell; and
one or more body segments defining a chamber through which the cryogenic fluid is to flow to the receptacle;
an insulation layer located radially between the one or more body segments and the outer shell;
a shaft having a first end and a second end, wherein the shaft is housed within and slidably extending through the chamber;
a poppet seat positioned adjacent to the front end of the body;
a poppet coupled to the first end of the shaft, wherein the poppet is configured to engage a receptacle poppet when the receptacle is coupled to the nozzle, wherein the poppet is configured to engage the poppet seat in a closed position and be disengaged from the poppet seat in an open position;
an actuator comprising a stem that is operatively coupled to the shaft, wherein the stem is configured to linearly actuate to cause the poppet coupled to the shaft to actuate between the closed position and the open position; and
a coupling assembly configured to couple the actuator to the back end of the body, wherein the coupling assembly includes insulating material to thermally isolate the actuator from the chamber through which the cryogenic fluid is to flow.
