How do i go about interfacing my controller with game to control motor drives and other input and output signals
All depends whether it's a PS4 or Xbox or some other controller.
Microsoft (XBox), for example, do provide documentation on how to develop games. For example: https://docs.microsoft.com/en-us/windows/uwp/gaming/racing-wheel-and-force-feedback
There are lots of examples online:
