You can do it this way too:

Modify your controller.java this way

Stage thisStage;

public void setStage (Stage stage){
    thisStage = stage;
}

public void showStage(){
    thisStage.setTitle("Titel in der MainController.java geändert");
    thisStage.show();
}

It is important that you don't use thisStage in the initialize method.

Modify your Mainclass this way:

@Override
public void start(Stage stage) throws Exception {
    URL location = getClass().getResource("Main.fxml");
    FXMLLoader fxmlLoader = new FXMLLoader();
    fxmlLoader.setLocation(location);
    fxmlLoader.setBuilderFactory(new JavaFXBuilderFactory());
    Parent root = (Parent) fxmlLoader.load(location.openStream());
    Scene scene = new Scene(root);
    stage.setScene(scene);
    MainController mainController = fxmlLoader.getController();
    mainController.setStage(stage);
    mainController.showStage();
}
