Sitecore - the controller for path was not found or does not implement IController

When attempting to load a Sitecore page via a content delivery server, the following error occurred:

Server Error in '/' Application.
The controller for path '[PageUrl]' was not found or does not implement IController.
Description: An unhandled exception occurred.
Exception Details: Sitecore.Mvc.Diagnostics.ExceptionWrapper: The controller for path '[PageUrl]' was not found or does not implement 

The cause of the error was a rendering on the page having an incorrect controller set. Fixing this was able to allow the page to load as expected.
