You can write your own Stage class with a return statement.

public class MyStage extends Stage {
   public String showAndReturn(myFXControll controll) {     
      super.showAndWait();
      return controll.getReturn();
   }
} 

After that you have to define a return function to your controller.

public class TableFilterControll implements Initializable {
    @Override
    public void initialize(URL arg0, ResourceBundle arg1) {
    }
    public String getReturn() {
        return "I'm a nice return value"; //return what you want controlled by your controller class
    }
}

Now you can controll your return from the parent controller.

String retValue=myStage.showAndReturn(childControll);

System.out.println(retValue);

I think this is a good solution for clean code. And you can style your FXML with Screne Builder.
