Zusammenfassung:	Methods and apparatus are disclosed for a low-emission nozzle and receptacle coupling for cryogenic fluid. An example nozzle (1200) includes a body (1240) defining a chamber through which cryogenic fluid is to flow. The body includes an outer shell (1245) that includes an outer shell surface. The nozzle includes a locking assembly (1210) configured to securely couple the nozzle to a receptacle. The locking assembly includes an inner sleeve (1230) fixedly coupled to the outer shell surface and comprising guide extensions (1233) and an outer sleeve (1214) extending over and rotatably coupled to the inner sleeve. One or more locking teeth (1215) are fixedly coupled to the outer sleeve and configured to be slidably received by respective one or more coupling slots of the receptacle. The one or more locking teeth are configured to rotatably slide within the respective one or more coupling slots to couple the nozzle to the receptacle as the outer sleeve rotates relative to the inner sleeve. Se describen métodos y aparatos para un acoplamiento de receptáculo y boquilla de bajas emisiones para fluido criogénico. Una boquilla de ejemplo incluye un cuerpo que define una cámara a través de la cual debe fluir el fluido criogénico. El cuerpo incluye una cubierta exterior que incluye una superficie de cubierta exterior. La boquilla incluye un conjunto de bloqueo configurado para acoplar de forma segura la boquilla a un receptáculo. El conjunto de bloqueo incluye un manguito interior acoplado fijamente a la superficie exterior de la carcasa y un manguito exterior que se extiende sobre el manguito interior y está acoplado de forma giratoria al mismo. Uno o más dientes de bloqueo están acoplados fijamente al manguito exterior y configurados para ser recibidos de manera deslizable por las una o más ranuras de acoplamiento respectivas del receptáculo. Los uno o más dientes de bloqueo están configurados para deslizarse de manera giratoria dentro de las respectivas una o más ranuras de acoplamiento para acoplar la boquilla al receptáculo a medida que el manguito exterior gira con respecto al manguito interior.
