• measuring a physical property by detecting information from the physical world
• receiving a signal from a device and performing a set action
• collecting data and then sending instructions for actions to be taken, or sending information for further analysis
• improving a physical environment by measuring changes

Explanation: The function of an actuator is to receive a signal (or instruction) from the controller, and based on that signal, perform a set action. Measuring a physical property is the function performed by a sensor. Collecting data from sensors and then sending instructions for further actions or sending collected data to another device for further analysis is the function performed by a controller.
