Abstract
An electrical submersible pump assembly has a number modules including a pump, a motor and a pressure equalizer. Each module has a rotatable shaft with a splined end that joins a splined end of another module, and those splined ends may differ in dimensions. A coupling that joins the shafts has a first shell has a splined bore that mates with the splined end of the first shaft. A second shell has a splined bore that mates with the splined end of the second shaft. An adopter has a first splined end in mating engagement with the splined bore of the first shell and a second splined end in mating engagement with the splined bore of the second shell. Fasteners secure the adapter to the shells. An annular seal isolates fluid communication between the first shell bore and the second shell bore.
