You have 2 errors:

• on_btn_clicked is a method of the class so it must have as the first parameter the instance, that is, self.

• the connection is with the name of the function without evaluating, in your case the slot on_action_clicked you are evaluating it, so you are getting it printed at the beginning, for it there are 2 possible solutions: use partial or use a lambda function.

    self.btn = self.window.findChild(QPushButton, 'pushButton')
    self.btn.clicked.connect(self.on_btn_clicked)
    self.action_save = self.window.findChild(QAction, 'action_save_state')
    self.action_save.triggered.connect(partial(self.on_action_clicked, 'action clicked'))
    # self.action_save.triggered.connect(lambda: self.on_action_clicked('action clicked')) # use lambda function
    self.window.show()

def on_action_clicked(self, txt):
    print(txt)

def on_btn_clicked(self):
    print('button clicked')
