Здесь, в первом действии, я загружаю изображение из камбуза. Когда я нажимаю на кнопку сохранения в своем Activity A, я хочу, чтобы он отправил изображение и передал его в мой класс адаптера

Создайте метод setImage в адаптере для bitmap, нажав кнопку save, вызовите метод adapter.setImage и передайте это изображение и сохраните его в адаптере. Вызовите notifyDataSetChanged() адаптера, чтобы обновить набор данных.
