1. A first adapter usable to remedy a defective first seal in an actuated fluidic control, the control comprising a control body, a control input disposed in a stem housing of the control body and sealed therein by the first seal, and an actuator releasably affixed to the control body, and arranged thereon to engage the control input, said first adapter comprising:
an adapter body having therein a transmission element for interconnecting the actuator with the control input, the transmission element comprising a control body-facing physical interface corresponding in shape to a physical interface of the actuator, and an actuator-facing physical interface corresponding in shape to a physical interface of the control input;
the adapter body further having a control-facing interface that is securably attachable to the control body, and an actuator-facing interface that is securably attachable to the actuator, such that the control input of the control, the transmission element, and the actuator's actuation interface are held in mutual engagement, wherein:
the control-facing interface of the first adapter is configured to fluidically seal against the stem housing of the control body, the adapter body further comprising a second seal, such that, when the first adapter is installed between the control body and the actuator, the second seal fluidically seals against the stem housing of the control body to prevent fluid leakage between the control body and the first adapter; and
the actuator-facing interface of the first adapter is mechanically complementary to the control-facing interface of the first adapter so that the actuator-facing interface of the first adapter is capable of mechanically mating with and fluidically sealing with a control-facing interface of a second adapter having the same control-facing interface and actuator-facing interface as the first adapter.
