Beschreibung
Zusammenfassung:	A method of lifting fluid by an electrical submersible pump (ESP) assembly in a wellbore. The method comprises positioning a first ESP component above the wellbore, wherein the first ESP component comprises a first drive shaft; positioning a second ESP component above the first ESP component, wherein the second ESP component comprises a second drive shaft; coupling a tethering assembly at a first end to an end of the first drive shaft proximate to the first flange; passing the tethering assembly through a coupling shell; coupling a second end of the tethering assembly to an end of the second drive shaft proximate to the second flange, wherein the tethering assembly is coupled slidingly to the first drive shaft or to the second drive shaft; coupling the first drive shaft to the second drive shaft by the coupling shell; and coupling the first flange to the second flange.
