The torque actuators that currently exist within OpenSim do not have an activation dynamics stage, meaning that the input directly affects the torque. If you want to create a new type of actuator, then you have to implement your own plugin. You can look into the OpenSim user guide for information on how to create your own plugins.

The next release of OpenSim will contain a CoordinateActuator with first-order activation dynamics; "ActivationCoordinateActuator". See https://github.com/opensim-org/opensim-core/pull/2699.
