Zusammenfassung:	Apparatus and method for increasing the torque capacity of threaded connections between tubular members. The apparatus may include a first tubular member (110) coupled with a second tubular member (200), and a torque member (300) wherein the torque member (300) is torqued against the second tubular member (200) and wherein tapered surfaces (122, 310) are engaged between the torque member (200) and the first tubular member (110) at a tapered surface interface. La présente invention se rapporte à un appareil et à un procédé permettant d'augmenter la capacité de couple et les connexions filetées entre des éléments tubulaires. L'appareil peut comprendre une première extrémité tubulaire couplée à une seconde extrémité tubulaire, ainsi qu'un élément de couple, l'élément de couple étant couplé contre le second élément tubulaire et les surfaces biseautées étant mises en prise entre l'élément de couple et le premier élément tubulaire au niveau d'une interface de surface biseautée.
