Something like this may work:

driver.find_element_by_xpath('//span[text()="Save"]')

But this will fail, if there is more than one button with text "Save" on the page.

In that case you may try to find some specific outer element (div, form, etc.) which does not change and contains the button. Then find the button inside of it.

With few requests with driver:

specific_div = driver.find_element_by_id("my_specific_div")
button = specific_div.find_element_by_tag_name("span")  # e.g. there is only one span in that div

Or with more specific xpath:

button = driver.find_element_by_xpath('//div[@class="some-specific-class"]/span[text()="Save"]')

If needed, search for more nested elements before the button, so you can get more narrow search field.
