1. An assembly comprising:
subsea equipment and a plurality of subsea electrical actuator devices each comprising an electrical actuator, each of which electrical actuator devices is individually mountable on and separable from the subsea equipment and includes a respective stab connector for establishing electrical connection with internal circuits of the subsea equipment and further has a respective terminal connector for a jumper lead to internal circuits of the electrical actuator device, each said electrical actuator device having at least dual redundancy whereby connection to a control module through the respective jumper terminal can substitute for the connection to a control module through the respective stab connector and internal circuits of said subsea equipment; and wherein the assembly includes a control module which can communicate with each of the said electrical actuator devices by way of the stab connections thereof and includes a terminal for at least one jumper lead for establishing a failsafe substitute connection to at least one of the said electrical actuator devices if a failure occurs in a connection between the electrical actuator device and said control module via said internal circuits of said subsea equipment.
