I see in the docs have :
With the exception of the Public context, creating a controller for your module for a specific controller is a simple as naming your controller to match the context. A controller for the content context, would be named content.php, while one that shows up in the settings context would be named setting.php. For the public context, the controller should be named the same as the module. For example, a Pages module would have a public controller called pages.php.
