Claim 0:
1. An electric submersible pump (ESP) assembly, comprising:
a first ESP assembly component comprising a first flange and a first drive shaft having first male splines at an end of the first drive shaft proximate to the first flange;
a second ESP assembly component comprising a second flange for attaching the second ESP assembly component to the first flange of the first ESP assembly component and a second drive shaft having second male splines at an end of the second drive shaft proximate to the second flange;
a coupling shell having a first set of female splines for mating with the first male splines of the first drive shaft and for coupling the first drive shaft to the second drive shaft, a second set of female splines for mating with the second male splines of the second drive shaft; and
a tethering assembly that is coupled at a first end to the end of the first drive shaft proximate to the first flange, passing through the coupling shell, and coupled slidingly at a second end to the end of the second drive shaft proximate to the second flange, wherein the tethering assembly defines a limit to the axial motion that can occur between the first ESP assembly component and the second ESP assembly component before the tethering assembly stops the axial motion, and where the tethering assembly is configured to support the weight of one of the first ESP assembly component or of the second ESP assembly component.
